Filtering compressor oil mist from air

[yenice]

I want to use a refrigerator compressor for creating vacuum. My compressor uses oil and positive pressure pipe blows air mixed with oil mist. If I want to use it indoors, how can I filter this oil mist from the blown air, so that my room is not contaminated with oil? One way is to use a pipe from the pump to outside but I want to use a filter. Is there a way?

For comparison, when you make make compressed breathing air from oily compressed air, you normally do it in three stages.

First, a water separator (that swirls the air so that the worst of the mist gets flung against, and then sticks to, the wall)

Then a coalescer (best to Google that one)

An finally an activated carbon filter to take the last of the odour out.

The separator and coalescer need periodic draining (with compressed air, you just blow them down - in your application, you'll need to rely on gravity). The odour filter needs periodic replacement.
